en.wikipedia.org/wiki/Mescaline

The article is off by 90 years here. Mitchell's well-known mescal/peyote account is "Remarks on the Effects of Anhelonium Lewinii (the Mescal Button)", and contemporary/archival references date it to December 5, 1896 in the British Medical Journal. A later historical review likewise states that Mitchell's description of his mescal experience "was published in 1896 in the British Medical Journal."

The sentence makes a blanket claim about Canada, France, the Netherlands, and Germany, saying that "anyone may grow and use peyote ... without restriction" because it is exempt. That is not true for France.

France's official legal text on Légifrance states that Annex IV of the narcotics list was amended to add "peyotl ou peyote" and its active principles/natural and synthetic compounds. In other words, peyote was specifically listed, not specifically exempted. An English-language legal overview from ICEERS likewise notes that in countries such as France, national drug laws restrict certain activities involving peyote.

Because the article uses a universal formulation across multiple countries, a single official counterexample is enough to make the statement false as written.

Attributing the Native American peyote exemption to the 1978 American Indian Religious Freedom Act is inaccurate.

Two legal sources contradict that formulation:

1. The U.S. Department of Justice explains that a DEA regulation under the Controlled Substances Act already exempted peyote use in Native American Church ceremonies.
2. Cornell's Legal Information Institute identifies the relevant statute as the American Indian Religious Freedom Act Amendments of 1994, enacted on October 6, 1994.

So the sentence points readers to the wrong legal instrument and date. The modern federal statutory protection for traditional Indian peyote use comes from the 1994 amendments, while the earlier religious exemption also existed through DEA regulation rather than being created by the 1978 act itself.
